Noticed this in Revelations a LOT. You know that guy who is banging away at the door to altairs library? His face shows up EVERYWHERE in the game. Whether it is citizen or guard. It is annoying too see. I recognise this in AC2 as well, however much less. Granted I am not saying that they should never re use character models, it just takes away from the experience when they are OVER used. I hope this isn't the case with AC3.
